Tasquinimod Biomarker Phase II data presented at ESMO 2012October 1, 2012 08:30 (CEST)
Lund (Sweden) and Paris (France), October 1, 2012. Active Biotech (NASDAQ OMX NORDIC: ACTI) and Ipsen (Euronext: IPN; ADR: IPSEY) have presented a new set of data on biomarkers from the previously concluded tasquinimod Phase II study in chemotherapy-naïve metastatic castrate resistant prostate cancer (CRPC) at the scientific congress ESMO (European Society for Medical Oncology) held in Vienna September 28-October 2.
Dr Michael Carducci, Johns Hopkins Medical Institute, Baltimore, US, presented on Saturday September 29 the poster "Tasquinimod mechanism of action biomarkers: Correlation with PFS and survival in men with metastatic castrate resistant prostate cancer treated in a randomized phase 2 trial*".
The purpose of this analysis from the phase II trial was to investigate the effects of tasquinimod on selected biomarkers to confirm preclinical findings on the mechanism of action. The results support an effect of tasquinimod on both immunomodulation and angiogenesis which positions tasquinimod as a potentially unique therapeutic approach with a mechanism of action that does not target the androgen receptor pathway.
The findings shall be further validated in the ongoing phase III placebo-controlled study in men with bone-metastatic CRPC, which has been adequately powered to detect an OS improvement. The study will include about 1,200 patients in more than 250 centers. Recruitment is proceeding according to plan with top line results expected by the end of 2013.

Tasquinimod has a pleiotropic mode of action which includes immunomodulatory, anti-angiogenic and anti-metastatic activity. Today the development of tasquinimod is principally focused on the treatment of prostate cancer. It was announced in December 2009 that the primary endpoint of the Phase II clinical study, to show a higher fraction of patients with no disease progression during the six-month period of treatment using tasquinimod, had been met. Phase II results were published in Journal of Clinical Oncology in September 2011.
About tasquinimod phase II
A global clinical trial 2:1 randomized, placebo controlled, double-blind Phase II trial investigating up to 1 mg/day of TASQ versus placebo in 206 asymptomatic patients with metastatic castrate resistant prostate cancer (CRPC). The primary endpoint defined as proportion of patients with disease progression at six months, was reached. The results showed that 6 month progression-free proportions for TASQ and placebo groups were 69% and 37%, respectively (p<.0001). The median progression free survival was 7.6 months for the TASQ group, compared to 3.3 months for the placebo group (p=0.0042). TASQ treatment also had an effect on biomarkers relevant for prostate cancer progression and was generally well tolerated. Analysis of up to three years safety data from the Phase II study, presented at the EAU February 2012, show that treatment side effects were mild to moderate (~ 5% of AEs grade 3-4), manageable and less frequent after two months of therapy. The adverse events observed included gastrointestinal disorders, primarily observed initially during treatment, fatigue and musculoskeletal pain. In June, 2012, overall survival (OS) data was presented at ASCO (American Society of Clinical Oncology).
About tasquinimod phase III
A global, pivotal, randomized, double-blind, placebo-controlled Phase III study of tasquinimod in patients with metastatic CRPC is ongoing. The aim of the study is to confirm tasquinimod's efficacy on the disease, with radiological Progression Free Survival (PFS) as the primary endpoint and overall survival as secondary endpoint. The study will include about 1,200 patients in more than 250 clinics. Recruitment is proceeding according to plan and top line results expected by the end of 2013.

Ipsen Forward Looking Statement
The forward-looking statements, objectives and targets contained herein are based on the Group's management strategy, current views and assumptions. Such statements involve known and unknown risks and uncertainties that may cause actual results, performance or events to differ materially from those anticipated herein. All of the above risks could affect the Group's future ability to achieve its financial targets, which were set assuming reasonable macroeconomic conditions based on the information available today.
Moreover, the targets described in this document were prepared without taking into account external growth assumptions and potential future acquisitions, which may alter these parameters. These objectives are based on data and assumptions regarded as reasonable by the Group. These targets depend on conditions or facts likely to happen in the future, and not exclusively on historical data. Actual results may depart significantly from these targets given the occurrence of certain risks and uncertainties, notably the fact that a promising product in early development phase or clinical trial may end up never being launched on the market or reaching its commercial targets, notably for regulatory or competition reasons. The Group must face or might face competition from Generics that might translate into loose of market shares.
Furthermore, the Research and Development process involves several stages each of which involve the substantial risk that the Group may fail to achieve its objectives and be forced to abandon its efforts with regards to a product in which it has invested significant sums. Therefore, the Group cannot be certain that favorable results obtained during pre-clinical trials will be confirmed subsequently during clinical trials, or that the results of clinical trials will be sufficient to demonstrate the safe and effective nature of the product concerned. The Group also depends on third parties to develop and market some of its products which could potentially generate substantial royalties; these partners could behave in such ways which could cause damage to the Group's activities and financial results. The Group expressly disclaims any obligation or undertaking to update or revise any forward looking statements, targets or estimates contained in this press release to reflect any change in events, conditions, assumptions or circumstances on which any such statements are based, unless so required by applicable law.
The Group's business is subject to the risk factors outlined in its registration documents filed with the French Autorité des Marchés Financiers.
